This study has been examined TMD using a leaf spring which is usually used in railway vehicle or cargo truck. In a first step of the study, the design indexes of leaf spring to apply for TMD was examined by the time history response analysis. As a result,the study investigated the specification of leaf spring for actual TMD. In the case of the design of coil spring, it was very difficult to be realized a practical used spring unit because of a manufacturable limitation of wire rod. However, it was confirmed that the design for TMD of the structure with long period is enough available by using leaf spring as a spring unit, considering properly the shape size including thickness of leaf spring and the maximum displacement of TMD.
